Normal Operation
The climate controlled seat module (CCSM) controls are incorporated into the dual automatic temperature control (DATC) module. The DATC module communicates with the CCSM via the UBP bus.

Possible Causes

- wiring, terminals or connectors.
- UBP network communication fault.
- DATC module.
- CCSM.
